The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Here at Outdoor Shopping we offer a large selection including GPS tracking locator navigation unit, portable tracker systems, GPS enabled wrist watches, detailed maps/atlases of your favorite hiking trails, accessory/mounting tools, international/domestic GPS software just to name a few. The handheld or mounted GPS system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. Some may have Bluetooth technology. A GPS wrist watch is a device with integrated GPS receiver that is worn as a single unit strapped onto a wrist, in the manner of a watch. The watch can have other features and capabilities depending on its intended purpose. GPS watches are most often used for sports and fitness purposes. A trail map is a map used to aid in navigation and can symbolize an assorted amount of information of a particular area or contain only a single representation of the data it represents. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it. GPS mounting tools are ideal for cars/boats to hold your GPS in place keeping your hands free. Software can be used on a laptop computer with an attached GPS receiver. Most commercial software runs only on Windows and Mac OS X, yet some projects have started to support Linux as well. For most daily use however, a PDA, a dedicated device, or a smartphone might be handier.
